About this deal

But as 5p a litre is about half the extra of ‘Premium’ fuel, it’s pretty cost-effective as a way of getting your fuel system to work more effectively. Strike three. Will we carry on using Redex?

In terms of economy, it’s almost impossible to be absolutely definitive as no two weeks are subject to exactly the same usage, weather or road conditions. Thankfully, now we’re finished, we no longer have a hung jury, with all three saying the C-Max is now noticeably smoother, especially when it, or the weather, is cold.Below is a table of my last recording before starting withthe Redex products, followed by one tank of the heavy-duty Redex Advanced 5-in-1 system cleaner and then six tanks using the regular Redex petrol system cleaner. My fuel economy figures haven’t shown any changes that could really be attributed to the Redex products. The variation of 3-4mpg above or below the average based on driving conditions and traffic outweighs any potential gain from the products. Again, if you were running a laboratory experiment that directly measured fuel consumption and removed all other variables then you may be able to show an improvement, but it’s nothing really noticeable.

The initial baseline figure of 30mpg is pretty indicative of my usual fuel economy result, although usually that’s relying on the car’s trip computer reading rather than direct measurement.The principle with the fuel system cleaner additives is that a clean fuel system will perform more efficiently than a clogged fuel system, much like your heart being able to pump blood more freely through clear arteries than clogged ones. Clogged arteries also mean your heart has to work harder and is at greater risk of heart damage, and your engine is no different. Over time, clogged fuel injectors can potentially lead to expensive engine damage. Over about 2,000 miles of mainly commuting in three months, my average fuel consumption using the Redex fuel system cleaners was 31.1mpg. My driving circumstances in that time have been a pretty representative example of my usual activities, so superficially it looks like a 1mpg improvement since using Redex. Our petrol and diesel fuel system cleaners are supplied in 250ml and 500ml sizes. The smaller 250ml version contains two doses / shots and the 500ml provides 4 shots. But the one question we’ve had from a number of readers since we first started using it is: Can using Redex damage my car? Each Redex bottle clearly shows how many shots it contains on the front label, with easy guide ‘shot’ marking on the side. Adding more than one shot of Redex won’t do any harm to your car and can give you a more intensive clean, so don’t worry if your pouring isn’t exact.

Given that your engine creates dozens of explosions every single second, there’s a lot of combustion going on under your bonnet. With any burning of fuel, there will be deposits and debris that forms. Sometimes it’s obvious, like the ash that forms when you burn a log in a fireplace. Other times, like in your car’s engine, these deposits are microscopic, but the principle is the same. Over time, these deposits build up and affect your ability to keep burning the fuel properly. Given that the additives I’ve been using are not performance boosters as such, I wasn’t expecting to feel any noticeable differences to my car’s accelerative qualities. If that was the point, Redex has products like its Petrol Power Booster. Alternatively, I could just fill my tank with premium unleaded fuel, which has a higher octane level than regular unleaded and provides extra power. When we did an interim report on the Redex test last month, we said that two out of the three regular users of the car thought it was running smoother, although one couldn’t notice any difference. As I outlined in previous reports, the type of fuel additive that I’ve been using is a fuel system cleaner rather than an octanebooster. The goal isn’t to turn regular unleaded into premium unleaded by increasing the car’s octane number, but simplyto give all the tiny pipes and injectors a thorough clean so they can do their thing without being clogged up. One shot of Redex fuel cleaner is capable of treating a fifty-litre fuel tank, but those who have never used a fuel additive before – or those who own an older car – may wish to use two shots for an intensive clean, particularly during first application.Our Redex experts or ‘RedExperts’ were recently asked “what is the mix ratio for Redex?”– the mix ratio for Redex is 1 shot per 50 litres of fuel, which equates to 2.5ml per litre of fuel. Take a look at our video. There has been no noticeable difference in performance, and I suspect you’d need a laboratory to really show any improvement. In the variable nature of the real world, and in a well-maintained modern car, I couldn’t detect any difference. After the initial 500mL dose of Redex Advanced 5-in-1 system cleaner, I have been adding a small 90mL bottle of Redex petrol system cleaner every time I have filled up my fuel tank for three months. In my situation, I don’t think I really need to keep using the additives at that rate in my car. I am likely to add a 90mL bottle every month or so and probably use the concentrated cleaner every six months to keep the Mazda’s fuel system sparkling clean. If I had an older car (or when this one starts getting older and higher-mileage), I’d keep using it every tank or at least every other tank. The second week of our test actually saw the mpg deteriorate by 1.5 mpg from the pre-test week, but it’s been a steady improvement since then and we look to be getting about 3mpg more than we did before. It’s not huge – about 6-7 per cent – but we’ll take it. Strike two. How much does it cost to use Redex?
